Not enough space in system partition.

I am trying to install a modded Google Play store via lucky patcher and I have 175 mb available in my system and for some reason any time I try and delete or change anything in the system folder it says "read only" so I am unable to get any more space in system.

And if you want to deactivate/remove what's commonly called bloatware, we highly recommend Package Disabler for Android. There's nothing for Apple, but it is possible to make preinstalled apps unavailable--do a search for instructions.
